308, Mathematics Research Center Building (ori. New Math. Bldg.)In our previous 2D CAD studies, the texture and speckle information are used to diagnose tumors and these features are classified by the neural network, support vector machine, data mining, and retrieval techniques. Recently, we dealt with 3D CAD techniques including 3D texture analysis, spiculation detection, and microcalcification identification. From these studies, using 3D techniques for CAD represents a potentially significant advantage over 2D. Vessels provide blood supply for tumor expansion and also increase the opportunity for tumor cells to enter the blood or lymph circulation. In contrast to normal vessels, tumor vasculature is highly disorganized, tortuous and dilated, with uneven diameter and excessive branching. We propose a method extracting morphological features from 3D breast power Doppler ultrasound and a CAD system adopting these features to classify tumor. Ultrasound elastography is a newly developed technique of imaging the tissue elasticity and it has been used clinically to examine a variety of breast lesions in patients. In general, the breast cancer tissue is harder than the adjacent normal breast tissue. Recently, we have developed a CAD for color elastography from Hitachi EUB8500. Recently, several companies such as Aloka in Japan and Usystems in USA have developed new whole breast ultrasound screening machines. We have developed a computeraided detection system for these fully automatic screening systems. By using the fullview images, our fully automatic CAD system for whole breast screening could be used to find suspicious frames and locate the approximate positions of tumors in the US images. By the way, an automatic rib detection will be introduced in this talk.

405, Mathematics Research Center Building (ori. New Math. Bldg.)In this lecture, we shall start more advanced part of the course. On the basis of observation that the Riemann invariants coincide with the end points of the bands in the spectrum of the Lame (or Schroedinger) equation, we relate the KdV equation with linear spectral problem and show that the KdV equation can be represented as a compatibility condition of two linear equations.

405, Mathematics Research Center Building (ori. New Math. Bldg.)An overview of the paper 〝Nonparametric Estimation of the Joint Distribution of Survival Time and Mark variables〞by Huang and Louis (1998) is given. They established a representation of the joint distribution function through the cumulative markerspecific hazard function and proposed nonparametric estimators. The finite and largesample properties of the estimators are also developed. A possible research topic and extension will be explored in this talk.
